摘要： An image decoding method according to the present invention comprises the steps of: generating a merge candidate list for a first block; selecting one from among merge candidates included in the merge candidate list; and performing motion compensation on the first block on the basis of motion information about the selected merge candidate, wherein inter region merge candidates included in an inter region motion information table can be added to the merge candidate list on the basis of the number of spatial merge candidates and temporal merge candidates included in the merge candidate list.

摘要： An image decoding method according to the present invention includes: a step for determining a reference sample line of a current block; a step for determining whether candidate intra-predition modes identical to the intra-prediction mode of the current block exist; a step for deriving the intra-prediction mode of the current block on the basis of the determination; and a step for performing intra-prediction on the current block on the basis of the reference sample line and the intra-prediction mode. Here, at least one of the candidate intra prediction modes may be derived by adding or substracting an offset to or from the maximum value among the intra-prediction mode of a neighboring block that is above the current block and the intra-prediction mode of a neighboring block that is to the left of the current block.
